## Key points

- A Heathrow screen displayed a sideways Linux boot log.
- The cause of the failure is unclear.
- Heathrow says newer displays use 30–40% less energy.

## Summary

A passenger spotted a Heathrow Terminal 2 information screen showing a sideways Linux boot log instead of maps or walking times. The fault highlights that the airport’s mixed fleet of display systems can fail on Linux as well as Windows, disrupting information travellers rely on.

The log mentions systemd, an Intel PRO/1000 network adapter and an EXT4 filesystem, but it does not reveal what caused the failure. Heathrow has been rolling out Raspberry Pi signage, though the hardware in this case is uncertain; the airport says its newer display approach is 30–40% more energy efficient and costs less than the previous hardware.
